Humanity should be grateful for the invention of Mac hotkeys. They probably saved us thousand years of time if put together. There is something addictive in using shortcuts - the quickness, the feeling of a keyboard, the geeky confidence in your fingers when you realize “hurray it works!” Once you get hooked on shortcuts, you’ll never go back to clicking again.

Roland Deschain (Idris Elba), the last Gunslinger, is locked in an eternal battle with Walter O'Dim (Matthew McConaughey), also known as the Man in Black. The Gunslinger must prevent the Man in. When I upgraded from Mac OS Sierra to High Sierra, had the same problems with the Apple mouse, but the Apple BT keyboard works fine. Turned off the BT mouse and used a generic Logitec wireless with USB dongle. It still had some problems. Plugged in a cheapo wired HP mouse and it works fine. Back up your Mac: This process will erase whichever OS you're currently using from your hard drive.

Basic Mac hotkeys combinations

1. Quit all apps

Sometimes an app that you thought you quit is still secretly running in the background. When your Mac lags and you need some fresh memory, you may choose to quit all apps. You probably heard of Force Quit (Cmd + Option + Esc), but it’s a too long way to do it.
Quit many apps in a row: Cmd + Tab

Then, holding down Cmd press Q to cycle between apps you need to close.

2. Delete a file completely

Dragging files to the Trash? Wait, this is not the only option. Here’s a shortcut to quickly delete unwanted files on a Mac, bypassing the Trash. Caution: there’s no way back.

To completely delete a file: Option + Cmd + Delete

3. Copy and paste a screenshot directly

Cmd + Shift + 4 is an old classic way to make a screenshot on a Mac. But here comes the combination to take your screenshotting skills to the new level. Normally you would make a screenshot, pick it from your desktop, and only then paste it to the new location. It appears, all this time you could do it easier.
To copy-paste a screenshot: Shift + Control + Cmd + 4

4. Quickly switch to the desktop

Sometimes your screen is so obscured by windows it would take years to click through to the desktop. Thank goodness, there is a Mac keystroke combination designed for people like us: the folks who are drowning in an ocean of windows.

To remove window overload: Cmd + F3

5. Open Spotlight

Spotlight, your Mac’s internal search engine, can make your life 1000% easier. It finds files faster than Finder and intuitively predicts what are you after. To open Spotlight right on the spot (sorry for the pun), use this magic combo.
To launch Spotlight search: Cmd + Space bar

4. Mac hot keys to invoke Siri

Among all Mac keyboard commands, this is the easiest. Since Siri’s arrival to macOS we got used to talk to Siri about weather and even ask her to play our favorite tracks on Mac. If you are using macOS Sierra or higher, you’ll enjoy the ability to summon Siri using just one hand.
To launch Siri: Cmd + Space bar

To open a new Chrome tab: Cmd + T

Mac shortcuts for documents

1. Copy text without formatting

You want to copy a piece of the text, but the old formatting drags along with it. Now you spend more time formatting rather than actually creating a text. To strip the text from old styling, use the following Mac hotkeys combination. A very good one to stretch your fingers.

2. Paste special symbols and emojis

Probably this is the easiest documented shortcut key for a Mac. To enter special symbols, like those lamdas, tildas, and alfas, you need to press just one key. For instance, if you need to type a modified E, hold down the E key for one second and then choose among available variations that appear.

To apply strikethrough formatting: Cmd + Shift + X

To invoke a print dialogue: Cmd + P

To move down the list of items in the sidebar, press VO-Down Arrow. When you hear the item you want, jump to it in the view browser; you can interact with it.

To jump, press VO-J. If you’re using VoiceOver gestures, keep a finger on the trackpad and press the Control key.

Move to and select the item you want to open, using the method for the view you’re in:

Icon view: Use the arrow keys to move to the item you want.
